DSS2 — Service 4.24: Query Federation Restore Status

When a federate receives an Initiate Federate Restore † callback, one of the supplied arguments of this service is a joined federate designator. So, as a result of the invocation of the Initiate Federate Restore † service, a joined federate's designator could change. This means that while a federate is in the Federate Restore In Progress state, its identity is basically undefined. Given that a precondition of the invocation of the Query Federation Restore Status service (clause 4.24) is that a restore is in progress, it is not clear what list of joined federate designators would be reported while a restore is in progress, nor is it necessarily clear at which federate the Federation Restore Status Response † service should be invoked. In fact, it is not clear that any meaningful information about the list of joined federates in the federation execution could be reported via the Federation Restore Status Response † service while a restore is in progress.

It should be pointed out that the behavior of this service is not testable.
